Pat Michaels says that Kyoto would destroy the US economy:
In a nutshell, that’s why the European governments are so exercised about Bush’s “no” to Kyoto. They see it as an international instrument that would destroy the economy of their major competitor, even as they know it doesn’t do a thing about global temperature. These facts are evident.
James Lovelock says global warming will make most of the planet uninhabitable
We are in a fool’s climate, accidentally kept cool by smoke, and before this century is over billions of us will die and the few breeding pairs of people that survive will be in the Arctic where the climate remains tolerable.
I reckon that they are both alarmists. William Connolley and James Annan have comments on Lovelock. Annan is rather harsh:
I hope that intelligent readers will see this for what it is – a plug for his new enviro-horror fantasy thriller, and not a scientifically meaningful comment any more than the execrable Crichton. It’s a shame to see formerly-respected scientists “go emeritus” (see here for another) but his past achievements do not immunise him from criticism.
